To Do. Should I also do traits without the detection probabilities?
For hummingbird species i feeding on plant species j observed at time k and sampling event observed by transect
Observation Model:
\[ Yobs_{i,j,k,d} \sim Binomial(N_{i,j,k},\omega) \]
Process Model:
\[ N_{i,j,k} \sim Binomial(\lambda_{i,j,k}) \] \[ logit(\lambda_{i,j,k}) = \alpha_i + \beta_{1,i} * Traitmatch_{i,j} \]

Using the counts from the transects. Abundance is especially important to model, since its fluctuating all the time.
Dashed line is the observed network from the time-series.
Dissimilairty in interactions (Beta_WN from Poisot 2012)
Dashed line is the observed network from the time-series.
Create a kind of venn diagram on PCA of model similarity based on per link discrepency.
